' Patented July 21, 19 53 V 2,646,035- smELD FOR NEUROCALOMETERS A George Anderson, Davenport, iowa My invention relates to a shield to be attached to-the fingers or prongs of a neurocalometer or any similar instrument and is preferably made of a transparent plastic, although it can be made j of glass, hardrubber or other suitable material,

and may also be applied to instruments such as vibrators or other instruments used in the treatment or observation of the spine.

I use th term neurocalometer to refer to an instrument of the class described and shown in Figure 6 of the patent to Dossa D. Egins, No. 1,552,284, issued September 1, 1925, for a process of spinal analysis. This form is shown in the drawing of this application.

In my drawings the neurocalometer includes a tubular housing 5 with a glass covered dial on the face thereof and with a pair of prongs 6-5 projecting from the body and carrying the terminals of a Wheatstone bridge system of wiring.

While my invention is intended primarily for application to the particular form of neurocalometer described, it is obvious that it may be applied to use with other forms of apparatus having a dial the View of which might be obstructed by the hair of a patient.

It is a matter of common experience among chiropractors that the hair of women as dressed in the present prevailing styles, is commonly of a length which interferes seriously with the operators vision of the dial of a neurocalometer when making a neurocalometer reading in the cervical region of the spine of a patient.

The objects of my invention are to provide convenient, easily applied meansto push and hold the hair away from the dial of a neurocalometer when so applied; to afford the Operator a clear vision of the dial while makinghis reading or tests for hot spots along the upper part of the spine; to provide such a shield which will not interfere with the operators vision of the dial, will be simple and economical and will be light and easy to apply and operate.

I accomplish these objects by the means illustrated in the accompanying drawings, in which,

Figure 1 is a front elevation of my shield mounted on a neurocalometer which is shown in outline;

Figure 2 is a sectional view on the line 2-2 of Figure 1;

Figure 3 is a top or plan view of my apparatus.

Similar numerals refer to similar parts throughout the several views.

My apparatus is preferably made from a sheet of transparent plastic of suitable thickness to stand up under pressure of the hair against it Application September 1, 1951, Serial No. 244,759

" 12 Claims. (01. 128-2.)

. 2 a and is preferably made by cutting a blank from sheet plastic of the required thickness, heating it with hot water or other suitable means, and

pressing it in a mold to the desired shape.

It comprises a base bar/l preferably narrow with arms '2 united thereto arranged to embrace the prongs 6 of aneurocalometer, and secure the shield against displacement.

A curved upright body 4 is united to the base as by a short curved section 3. The body?! inclinesirearwardly at a small angle and is of suffi-v cient height and so spaced as to move, the. hair at the back of a woman patients head'out' of the line of vision from the operators eyes to the dial of the neurocalometer, thus permitting a clear and unobstructed View of the dial and greatly facilitating the use of the neurocalometer.

Glass or any transparent material of sufficient stability may be used in place of plastic, or hard rubber, aluminum or other opaqu material may be used-if desired, as the line of vision of the operator will usually lie in the rear'of the body of the shield rather than through the body.

In the operation of my shield, it is mounted upon the prongs of a neurocalometer and the ends of the prongs are applied to the neck or body of the patient on opposite sides of th spine in the usual way. The neurocalometer is then glided along the spine in the usual well known manner to detect hot spots, and when it reaches the hair at the back of the neck or head, it Will lift the hair and hold it out of contact with the dial of the neurocalometer far enough to afford the operator a clear view of the dial.

I claim:

1. A shield for neurocalometers or similar instruments as described, comprising a narrow base, lateral arms united to the base curved downwardly and adapted to embrace the prongs of 'a neurocalometer, and a curved body united to and extending upwardly from the base.

2. A shield for neurocalometers as described, comprising a base, lateral arms united to the base curved downwardly and adapted to embrace the prongs of a neurocalometer, a curved body united to and extending upwardly from the base and inclined rearwardly.

3. A shield for neurocalometers as described in claim 2, said body being curved in an arc corresponding to a periphery of the neurocalometer. I 4. A shield of thin transparent material for neurocalometers as described, comprising a narrow base, lateral arms united to the base curved downwardly and adapted to embrace the prongs 3 of a neurocalometer, and a curved body united to and extending upwardly from the base.

5. A shield of thin transparent material for neurocalometers as described, comprising a narrow base, lateral arms united to the base curved downwardly and adapted to embrace the prongs of a neurocalometer, a curved body united to and extending upwardly from the base and inclined rearwardly, said body being curved in an arc corresponding to the periphery of a neurocalorneter.

6. A shield of transparent plastic for neurocalometers as described, comprising a narrow base, lateral arms united to the base curved downwardly and adapted to embrace the prongs of a neuro'calometer, and a curved body united to and riphery of a neurocalometer.

7. A shield for neurocalometers as described,

comp-rising a narrow base, arms united to the base adapted to embrace the prongs of a neurocalometer, and a curved body united to and eX- tending upwardly from the base and arranged to contact the back hair of a patient and hold it away from a dial when in use.

8. The combination with a neuro-calometer having a cylindrical body with a dial face plate in the upper end thereof and a pair of projecting prongs united to the body, of a shield having a base bar, lateral arms united to the base bar curved downwardly and embracing the projecting prongs, and a curved body united to the base bar extending upwardly over a part of the dial at an angle to the dial.

arms united to the base bar curved downwardly and embracing the projecting prongs, and a curvedbody united to the base bar extending upwardly over a part of the dial at an angle to the dial. 1

12. The combination with a neurocalometer A having acylindrical body with a dial face plate in .therupper end thereof and a pair of projecting prongs united to the body, of a shield of transparent plastic having a base bar, lateral arms united to the base bar curved downwardly and emrbacing the projecting prongs, and a curved body united to the base bar extending upwardly overa part of the dial at an angle to the dial.
